Apache Pulsar joins Kafka in Splunk Data Stream Processor

Splunk developed out its occasion streaming capabilities with a new update, introduced Wednesday, to its Knowledge Stream Processor to provide in a lot more knowledge for evaluation on the Splunk platform.

The DSP engineering is a foundational part of the info safety and occasion administration vendor’s Knowledge-to-Every thing approach. The new launch, DSP 1.1, incorporates a sequence of enhancements together with better integration to ingest knowledge from Microsoft Business 365.

Pulsar compared to Kafka

The DSP update also positive aspects from Splunk’s October 2019 acquisition of streaming knowledge seller Streamlio, a chief of the open up resource Apache Pulsar streaming knowledge task. Pulsar is often witnessed as a rival to Apache Kafka, even though the Splunk Knowledge Stream Processor now integrates equally systems to allow its occasion streaming capabilities.

 “Although Kafka definitely has the edge over Pulsar in terms of market place existence and consumer traction, proponents argue that Pulsar’s decoupled architecture provides it with general performance strengths over Kafka, though it also offers sound message queueing and multi-tenancy functionality,” mentioned Matt Aslett, research director at S&P Global Industry Intelligence. “Like Kafka, Pulsar has also been growing at a quick tempo over and above uncomplicated messaging.”

Splunk is rather new to the stream processing specialized niche, but it has ambitions to generate significant business from Knowledge Stream Processor, over and above uncomplicated integration and company-broad knowledge shipping and delivery, with higher emphasis on delivering automated steps, Aslett mentioned.

Pulsar occasion streaming boosts Splunk DSP

Splunk has been occupied integrating Apache Pulsar as a foundational ingredient for occasion stream processing and knowledge collections, mentioned Josh Klahr, vice president of product or service administration at Splunk.

“There are specific use cases the place Pulsar operates very properly when in comparison against Kafka,” he mentioned. “What Pulsar provides is a little a lot more resilience for stateful employment.”

For instance, Klahr mentioned Pulsar is properly-suited for a consumer executing a significant-scale knowledge lookup and carrying out enrichment on the stream. He argued that Pulsar is also often better than Kafka when there are latency issues with a knowledge link that could drop intermittently. With knowledge interruptions, Pulsar can handle latency by storing knowledge on a node till a link will become steady.

“Pulsar tends to make certain that there is a assured shipping and delivery of all the messages throughout the community,” Klahr mentioned.

Splunk DSP 1. had previously built-in assistance for Kafka as an occasion streaming knowledge engineering. With DSP 1.1, buyers will now get the positive aspects of equally Kafka and Pulsar, with no owning to opt for a single or the other solely.

“The decision about what occurs in the back again close is type of abstracted away when buyers are making knowledge pipelines,” Klahr mentioned. “There is certainly not a certain preference that the consumer requires to make about how the processing is performed.”

Splunk Knowledge Stream Processor 1.1 updates

Beyond the Apache Pulsar integration, Klahr discussed that Splunk’s target for the new DSP launch is to make knowledge a lot more available.

A single of the knowledge sources that is now a lot more available in DSP 1.1 is Microsoft Business 365. Splunk has had other approaches of obtaining knowledge from Microsoft Business 365, together with utilizing an agent as an endpoint knowledge collector, Klahr mentioned. Even so, that approach failed to permit for knowledge manipulation, enrichment or alerting on the knowledge coming from Business 365 as an occasion stream.

The variety of knowledge that Splunk buyers have a tendency to pull from Business 365 incorporates audit logs for Energetic Listing, services status info as properly as knowledge from the administration API that can be helpful for safety visibility.

“Now, with DSP 1.1, we are offering a a lot more modern way to get that knowledge from Business 365,” Klahr mentioned.
